Description

CYLINDER LOCK WITH MODIFIED CAM}

The present invention relates to a cylinder lock, and more particularly, to a cylinder lock with a sleeve which is installed to move along a cylinder lock body and meshes with a helical cam of the cylinder lock to change the rotational movement of the key to linear movement.

Cylinder locks have been in use for over 100 years as a standard device for locking doors and containers. Shown in FIG. 1 is a conventional European double cylinder lock device 30.

The double cylinder lock device 30 of FIG. 1 has a key 32, a double cylinder lock 34 and a cam 36. The standard element installed in the cylinder lock 30 is shown in FIG. 2, in addition to the rotary cylinder plug 35 (FIG. 1) fixed in place by the circlip 38, and the coupling 40 mounted therein. Rotating cam 36. Elements such as pins and springs are not shown.

The double cylinder lock device 30 operates as follows. When the key 32 is inserted into the cylinder lock 34 and turned, the cam 36 rotates. In the case of door locks, this rotation causes the bolt (not shown) to move in the tangential direction in which the cam 36 moves. As the bolt moves into or out of the door frame, the door is locked or released. In short, in the past, the locking bolts were moved to tangential movements.

However, this conventional cylinder lock is only one kind. Many have changed the shape and size of the existing cylinder lock.

In the prior art of FIG. 3, a gear 44 is fitted to a double cylinder lock, which was introduced in US Patent No. 3,991,595 dated November 16, 1976. The difference from the apparatus of FIG. 1 is that the gear 44 is mounted on the cylinder lock 34 instead of the cam 36. The advantage of the cylinder lock 34 fitted with the gear 44 is that the torque required to move the large or multiple locking bolts is small. Instead of turning the key once to get the force needed to move the bolt, the gear 44 actuates the reduction gear, allowing the user to move the bolt more easily, thereby dispersing the force required to move the bolt over longer distances.

4, only the gear 44 in FIG. 2 is changed, and the circlip 38 and the coupling 40 are the same.

U.S. Patent 4,154,070 of May 17, 1979 introduces a lock that fits several bolts into the door frame in various directions. The disadvantage of this design is that it requires a large space to install the device, which makes it difficult, time consuming and expensive, and the door structure itself is weak, thus reducing the overall security. The metal plate that makes up this lock is not strong.

Thus, there is a need to improve cylinder locks to be more compact with stronger materials at reasonable prices. Miniaturization allows the doors to be manufactured worldwide using parts from standard cylinder locks, with minimal locks on the doors.

Accordingly, a main object of the present invention is to provide a cylinder lock having a body and a cam while overcoming this problem in the related art and moving the external element engaged with the cam to slide the external element along the body.

The cylinder lock of the present invention is compact in design and can produce various kinds of locks at low cost, and can surround the entire cylinder lock with a case to sufficiently protect it from external intrusion or damage. The cylinder lock encased in the case can be easily installed without weakening the door structure, and the production process is simplified and the manufacturing cost is reduced by using as many standardized parts as possible.

According to the present invention, there is provided a cylinder lock having a body and a cam, the outer element sliding axially in the body to engage the cam.

According to the present invention, since the cylinder lock uses a helical cam, this is hereinafter referred to as HC cylinder lock. When the key is inserted into the HC cylinder lock and turned, the movable sleeve moves in the longitudinal direction of the cylinder lock to change the rotational motion into a linear motion. This linear motion is used to move the locking bolt, and the sleeve itself may be the locking bolt.

Since the screw groove coupled to the helical screw section formed in the helical cam is formed in the movable sleeve, the sleeve and the cam are engaged.

In the HC cylinder lock of the present invention, the door lock having the HC cylinder lock can be installed by utilizing the internal space of the door more efficiently, since the streamlined design makes it easy to install in the door interior space.

On the other hand, the projection protruding radially from the rotation of the cylinder lock can engage the helical slot formed in the outer element.

In addition, the wing section may protrude integrally with the outer element. There is an inclined surface in the wing section, which is arranged to move the locking bolt in a direction orthogonal to the axis of the body in response to the axial sliding of the outer element.

In this case, a diagonal slot is formed in the wing section between the proximal end and the distal end of the cylinder body. A non-inclined portion is formed at the proximal end and the distal end of the diagonal slot, the non-inclined portion of the proximal end operates a spring latch, and the non-inclined portion of the distal end enables the double locking function.

The cylinder lock of the present invention provides various door locking mechanisms, for example, a security lock installed on an outer surface of a door and using a locking latch. This locking mechanism is operated by HC cylinder lock on one side of the door and protects the entire locking mechanism from intrusion by enffjTK with the case. The locking bolt of the locking mechanism is operated by the movement of the sleeve-like element moving axially along the HC cylinder lock body.

The HC cylinder lock of the present invention is also used in a locking mechanism using a plurality of locking bolts, in addition to the locking bolt, it is also arranged a spring latch operated by the HC cylinder lock key or door handle.

As another example, the HC cylinder lock of the present invention may be installed in a padlock substitute, wherein the multibolt locking mechanism is fixed to the door from the outside. The multibolt locking mechanism uses a sleeve that slides the body of the HC cylinder lock to move multiple locking bolts. The locking bolt of the locking mechanism engages the locking latch installed on the door frame. The entire HC cylinder lock and locking mechanism can be surrounded by a case to protect against illegal intrusion or damage.

The prior art with reference to FIGS. 1 to 4 has been described above.

In the cylinder lock of the present invention of FIG. 5, the cam is deformed so that the outer element can slide along the body of the cylinder lock.

A preferred embodiment of the present invention is a double cylinder lock 34 in which movable sleeves are arranged (see FIGS. 7 to 9), in which a conventional cam 36 or gear 44 is replaced by a helical cam 48. The cam has a helical screw section. The screws of the helicom cam 48 are left or right screws, and the pitch is variable. Four right-hand screws are formed in the helical cam 48 of FIG. When the key is turned fully, the movable sleeve moves about 30mm along the body of the cylinder lock, and the body is 76mm long.

5 shows how to install the helical cam 48 in the standard double cylinder lock 34 (hereinafter referred to as HC lock). It is important to install the helical cam 48 on the cylinder plug 35 in the same way as the circlip 38 instead of the standard cam 36 or gear 44 that is conventionally used for the cylinder lock. Similarly, since the inner space 50 of the helical cam 48 coincides with the inner space of the standard cam 36 or the gear 44, the coupling 40 may be fitted into the inner space 50. The advantage of this design is that only a small number of parts can be changed or replaced to implement new technology in existing locksmithing or production facilities.

The axis A-A of FIG. 5 is a line passing through the center of the circular portion of the cylinder lock 34, that is, the center of the section with the key groove, and coincides with the center of the helical cam 48. After that, the "axial direction" may be understood as the A-A line direction.

FIG. 6 is an exploded view of the HC cylinder lock 34 of FIG. 5, showing the cam 48, the coupling 40, and the circlip 38.

7 is a perspective view of the cylinder lock, in which the movable sleeve 52 slides along the body of the HC cylinder lock 34. The female thread 54 of the movable sleeve 52 engages with the male thread formed in the helical cam 48.

The device equipped with the key 32, the double cylinder lock 34, the helical cam 48, the movable sleeve 52, and the like is hereinafter referred to as movable sleeve type HC cylinder lock 46.

When the movable sleeve type HC cylinder lock 46 is operated, turning the key 32 in the cylinder lock 34 rotates the helical cam 48 while the male screw of the helical cam rotates with the male screw 54 of the movable sleeve 52. To interlock. By such engagement, the rotational movement of the helical cam 48 is changed to the front or rear linear movement of the movable sleeve 52 according to the rotational direction of the key 32. The inner diameter of the cylindrical sleeve 54 is such that it fits into the body of the HC cylinder lock 34 to guide linear movement with minimal friction.

8 to 9 are perspective views of the movable sleeves 52 respectively positioned at the front and rear ends of the HC cylinder lock 34 body.

In FIG. 8, the movable sleeve 52 is located in front of the HC cylinder lock 34. When the key 32 is turned 360 degrees, the movable sleeve 52 moves along the HC cylinder lock 34 by the rotation of the helical cam 48. Turn the key 32 completely to remove it.

The sleeve 52 of FIG. 9 is in the position after the key 32 has been fully turned. That is, it moves axially from the front end to the rear end of the HC cylinder lock 34.

The profile 53 of the HC cylinder lock 34 of FIG. 8 is different from the profile 56 of the cylinder lock of FIG. 9. This change is intended to illustrate the concept of cylinderlock profiles. In addition, there is no fear that the sleeve 52 may move excessively and detach from the HC cylinder lock 34 because the movement of the sleeve 52 is guided by a housing (not shown).

10-12, the single cylinder lock 60 is shown. Attached to the single cylinder lock 60 is a modification of the sleeve of the movable sleeve HC cylinder lock 46. Compared with the movable sleeve 52 described above, the sleeve 62 is reinforced with an end 64, and this reinforced end serves as a locking bolt. The reinforcement end sleeve 62 also has the same helical screw 54 and has the same diameter as the movable sleeve 52.

The device with the key 32, the single cylinder lock 60, the rotary cylinder plug 61, the helical cam 48, the end reinforcement sleeve 62 and a common cylinder lock inner element (not shown) is referred to as end reinforcement sleeve Type HC cylinder lock 58 is referred to.

An advantage of the end reinforcement sleeve type HC cylinder lock 58 is that it can be used as a locking bolt as described below.

The end reinforcement sleeve type HC cylinder lock 58 of FIG. 11 is in the retracted position where the end reinforcement sleeve 62 is closest to the key 32.

The key in FIG. 12 is rotated once and the end reinforcement sleeve 62 is in an extended position away from the key 32 by moving in the axial direction. This stretch mode is used for locking as described later.

In the end-reinforced HC cylinder lock 58, it is not necessary to completely turn the key 32 to obtain the desired motion. Even if the key 32 is turned 90 degrees, which is about 1/4, the end reinforcement sleeve 62 can be moved by 7.5 mm, so that the key 32 can be sufficiently locked.

13 to 15 show another structure in which the movable sleeve operates in a rotational-linear motion as in the prior art. The device has a key 32, a single cylinder lock 68, a pin 70, a roller 72, a helical slot end reinforcement sleeve 74 and other internal elements (not shown), helical slot end reinforcement sleeve type It is called cylinder lock 66.

The helical slot 76 of the end reinforcement sleeve 74 is helically formed in a portion of the length of the sleeve. The angle of the helical slot facilitates the axial movement of the sleeve as described below. The helical slot end reinforcement sleeve 74 is mounted on the single cylinder lock 68, and the pin 70 is fitted to the cylinder plug 35 so as to rotate together. Fit the roller 72 to the pin. The roller 72 is inserted into the helical slot 76 of the helical slot end reinforcement sleeve 74 and rolls along the length of the helical slot to reduce friction during movement of the pin 70.

In operation, the helical slot end reinforcement sleeved cylinder lock 66 is in the extended locking position of FIG. If the key 32 is turned on the single cylinder lock 68 and turned about 1/4, the key cannot be taken out. Pin 70 rotates with cylinder plug 61 in the same amount. It is important that the pin 70 does not move axially relative to the cylinder lock 68. When the pin 70 rotates in the helical slot 76, the sleeve 74 moves axially (see FIG. 16). Sleeve 74 is in the retracted position relative to cylinder lock 68 (see FIG. 15). Here, both ends of the slot 76 restrict the movement of the pin 70, so that the key 32 also rotates only 1/4.

The helical slot reinforcement sleeve-type cylinder lock 66 is used for the locking function in the extended position, wherein the reinforcement end 78 of the sleeve 74 is used as a bolt, which will be described later.

16 to 17 show an application of the helical slot, end reinforcement sleeve cylinder lock 66.

The lock shown in FIG. 16 is a pivot bar lock 80 surrounding a helical slot end reinforcement sleeve cylinder lock 66. This cylinder lock 66 is installed inside the pivot bar 84. Pivot bar 84 may rotate about 90 degrees in the direction of arrow 92 and is mounted to clasp 82. Clasp 82 is fixed to the door 88 with bolts 83, clasp 86 is fixed to the door frame 90 with bolts (85). The cross section 94 is for easily positioning the cylinder lock 66 to the pivot bar 84.

17 shows the detachable portion 100 of the pivot bar 84. Rotate the pivot bar 84 and fasten it to the catch 86 which is fixed to the door frame 90.

When the key 32 is inserted into the cylinder lock 66 and turned, the end reinforcement sleeve 74 moves to the opposite side of the key 32, and the reinforcement end 78 enters the circular space 96 of the clasp 82, and the sleeve 74 is rotated. Acts as a bolt. When the sleeve 74 enters the clasp 82, the pivot bar 84 does not rotate and the lock is released.

Likewise, pivoting the pivot bar 90 degrees in the direction of the arrow 92 from the clasp 86 by turning the key 32 and inserting the sleeve 74 into the groove 98 allows the pivot bar lock 80 to be locked in the open position. have. In the open lock position, the lock is prevented by anyone other than the holder of the key.

As will be appreciated by those skilled in the art, the end reinforcement sleeve-type HC cylinder lock 58 of Figs. 10 to 12 may be applied to the application examples of Figs.

18 is a modification of the movable sleeve HC cylinder lock.

The device is equipped with a key 32, a double HC cylinder lock 34, a helical cam 48 (not shown), a wing sleeve 104, and the like, hereinafter referred to as wing sleeve HC cylinder lock 102.

The female thread 54 of the wing sleeve 104 is similar to the female thread 54 of the movable sleeve 52 and can be moved by the helical cam 48 as before. Unlike the cylindrical movable sleeve 52, the wing sleeve 104 has three identical slot wings 106. These wings may differ in shape from one another, and may have different numbers of wings or slot inclinations. The slot wing 106 has a slot 108 formed in a diagonal direction, and the non-inclined portion 110 parallel to the axial direction is formed at the distal end thereof. Due to the terminal non-tilt 110, double locking bolt operation is possible.

When in use, turning the key 32 causes the helical cam 48 to rotate to move the wing sleeve 104 in the axial direction. The wing sleeve 104 indicated by the broken line 112 indicates the position after the key 32 is rotated to move in the direction of the arrow 114. The wing sleeve 104 is positioned at the edge of the HC cylinder lock 34 as indicated by the broken line 112.

19 is an exploded perspective view of a security multibolt lock with wing sleeve HC cylinder lock 102.

The wing sleeve 104 is provided in the HC cylinder lock 34, and the bolt holder 118 is located on the distal non-inclined portion 110 of one slot wing 106. The bolt holder 118 is fixed to the wing sleeve 104 by a screw 120 screwed into the lower threaded portion of the bolt holder 118 through the slot 108 of the wing sleeve 104. The bolt holder 118 also has a threaded portion 122 for fitting the bolt 124. The bolt 124 and the bolt holder 118 may be assembled, and the length of the bolt 124 may be as desired.

The advanced multibolt lock with wing sleeve HC cylinder lock 102 has an outer housing 132 and an inner housing 134. The HC cylinder lock 34 is placed in the space 136 of the inner housing 134 and fit into the space of the outer housing 132. The profile 53 of the HC cylinder lock 34 also fits into the space 138 of the inner housing 134 and the space of the outer housing 132.

The wing 106 of the wing sleeve 104 fits into the space 140, 142, 144 of the inner housing 134 and the space of the outer housing 132.

The outer end of the cylinder plug 35 is protected by the rotary shield plate 146.

The flange 152 of the outer housing 132 and the flange 150 of the inner housing 134 abut together and are tightened with screws 148.

Cover the outer cover plate 154 to the outer housing 132 and tighten the screw 158 in the hole 160 to be fixed to the inner cover plate 156 through the door. External elements such as outer cover plate 154 or rotating plate 146 should be made of a rigid material to prevent intrusion.

20, the screw 120 of the bolt holder is located in the non-inclined portion (110). The purpose of the non-inclined portion 110 of the slot wing 106 is to take a separate double locking operation of the bolt 124 well. Together with the bolt holder 118 located at the non-inclined portion 110, the bolt 124 is completely embedded in the door frame, to secure the door in place.

Referring to FIG. 21, the bolt holder 118 is positioned at the bottom of the diagonal slot 108, and the bolt 124 is completely retracted from the door frame to unlock the door.

When the key 32 is turned clockwise, the wing sleeve 104 moves in the direction of the arrow 166, and the bolt holder 118 descends along the slot 108. Importantly, the bolt holder 118 is moved only radially and not axially by the spaces 140, 142, 144 formed in the housings 134, 132 (see FIG. 19). The bolt holder 118 moves from the position of FIG. 20 to the position of FIG. 21 (ie, the lower position of the slot).

Subsequently, turning the key 32 counter-clockwise (eg counterclockwise) causes the wing sleeve 104 to move axially toward the key 32 while the bolt holder 118 moves along the slot 108 to the non-inclined portion 110. To rise. As described above, the bolt holder 118 moves only in the radial direction and not in the axial direction by the spaces 140, 142, 144 formed in the housings 134, 132.
